erases.

To all whom it may concern:

Be it known that I, CHARLES BILLINGTON, citizen of the United States,residing at Attleboro, in the county of Bristol and State oflvlassachusetts, have invented certain new and useful Improvements inEyeglass Connections, of which the following is a specification.

This invention relates to eyeglass connections, and its object is toproduce of bendable sheet metal a one-piece form or yoke, having partsof special construction and arrangement for adj ustably supporting thetwo lenses of an eyeglass, parts of the sheetmetal form being alsoprovided to pivotally carry handoperated nosegrips and the coiledsprings which act thereupon.

The stated object is accomplished by fashioning a fiat piece of metalinto substantially the contour illustrated in the accompanying drawings,of which Figure l is a plan view of the form before any portion has beenbent. Fig. 2 represents a side view of one end portion of the form afterthe parts at that end have been bent to receive the lens. The coiledspring is shown upon the curved arm constructed to carry it. Fig. 3 is aview from above the same end of the form as shown in Fig. 2. Fig. A is aview from above of an eyeglass showing the two lenses connected by thisinvention, and exhibiting also the pivoted nose-grips. Fig. 5 is an endView of the invention in the shape illustrated in Fig. A, but omittingthe lens.

The same letter refers to the same part throughout the drawings andspecification.

Fig. 1 sets forth the form as it appears before any of its projectingparts have been bent. The bow or curved middle portion is marked A, andtwo eyes B and b are near the ends of the curved portion A.

Extending transversely at the ends of the middle portion A are straightparts C and o, and at right angles with those transverse parts the armsD and cl project outwardly. At the top of the portion C there is formedthe double curved arm E having an end eye F. At the lower end of theportion C there is formed a single curved arm G having the end eye H.The portion 0 is provided with like extensions designated by letters 6,f, g, and it.

Let it be assumed that the portion 0' is turned up at the line of itsjuncture with the middle A, until the surface of portion 0 Specificationof Letters Patent.

is perpendicular with the surface of the middle portion A. Then, supposethe portion 0 to be curved as illustrated in Fig. 2 until it coincideswith the curvature of the lens at the end of the lens, and the arms aand 9 arranged on opposite sides of the lens, with eyes f and h oppositeeach other, as best shown in F 4;. It is believed to be now clear thatit the hole in the lens be located a slightly greater or less distancefrom the edge of the lens than the prescribed distance, the arms 6 and 9may be adjusted to allow for such variation, bringing the eyes f and gto register exactly with the hole through the lens.

In Fig. 3 it will be observed that the originally straight projectingarm (Z is curved, approximately upon the are 01 a circle, and that thecoiled spring j is arranged about the arm (Z, the outer tip of the armbeing bent slightly to retain the spring. In Fig. 8 it will be furtherobserved that the eye 6 previously mentioned is bent into a positionperpendicular to the surface of the middle A. It will be noted also thatthe parts referred to by letters D, E, F, G, H, and J, corresponding tothe parts illustrated in Figs. 2 and 3 and described above, are arrangedcorrespondingly on the other side of the middle A, as shown in Fig. 4.

To the eyes B and o are pivotally secured the nose-grips K having thefinger piece L and M having a similar finger piece N. This arrangementof the parts is best shown in Fig. A.

In the operation of this invention, the finger pieces L and N upon oneside of the middle or bow A are caused to approach each other, thusseparating the nose grips K and M upon the other side of the middle A.At the same time, the springs J and j are compressed.

As shown in Fig. 5, the arm D passes through a slot is in the nose gripK, but the slot is not large enough for the spring to pass also. Theslots permitting the passage of arms D and cl occupy the same positionswith respect to the nose grips K and M. The slot 71: only is shown, butthere is a corresponding slot through the nose grips M. The result isthat the spring is compressed, and its reaction forces the nose-griptoward its original position and grasps the nose of the weareryieldingly.

As previously stated, the arms D and d are bent into the arc of acircle. They both have the same curvature. The pivotal points of thenose-grips are the centers of the circles, and the slot is and itsfellow, not shown, need be, therefore, only slightly larger than thecross-section of the arms to permit the movements of the nose-grips asexplained and the compression of the springs J and as set forth. WVhileit is true that the ends of the arms D and (Z project through thenose-grips when the nosegrips are caused to approach each other, thedistance between those ends is intentionally made a little greater thanthe width of the nose of the wearer, by bending bow A. The

ends of the arms do not touch the skin. Considering Figs. 3 and 4, itwill be noted that the full extension of springs J and j press thenose-grips K and M toward each other for a small distance beyond theends of the arms D and (Z. This distance is amply sutficient to effectan adequate yet gentle clasp of the nose by the nose-grips.

Having now described this invention and explained the mode of itsoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. In an eyeglass connection, a one-piece sheet metalform having a middle curved portion and transverse portions located atthe ends of said middle portion, means borne by said transverse portionsand constructed and arranged to engage a lens, the said transverseportions having arms extending toward each other, coil springsencircling the said arms, and nose-grips pivotally supported adjacent tosaid arms and having portions arranged in contact with said springswhereby the springs are compressed when the nose-grips are separated.

2. In an eyeglass connection, a one-piece sheet metal form having amiddle curved portion and transverse portions located at the ends ofsaid middle portion, means borne by said transverse portions andconstructed and arranged to engage a lens, the said transverse portionshaving curved arms extending toward each other, coil springs encirclingsaid arms, and nose-grips pivotally supported adjacent to said arms andhaving portions provided with slots and arranged in contact with saidsprings, the said arms passing through the said slots, whereby thesprings are compressed when the nosegrips are separated.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES BILLINGTON.
